    2,Financial文件格式

    root@demo-1:~/flash_seq# cat Financial|head
    0,303567,3584,w,0.000000
    1,55590,3072,w,0.000000

    0,303595,3584,w,0.550502
    $1 Application specific unit (ASU) 设备号
    $2 Logical block address (LBA) 逻辑块地址
    $3 Size 请求的数据长度
    $4 Opcode 读请求或者写请求,WebSearch中只有读请求,Financial
    $5 Timestamp 请求下达的时间戳

    3,解析

    统计第一列的磁盘阵列情况

     awk 'BEGIN{FS=","};{print $1}' Financial1| sort |uniq -c|head
     153566 0
     435222 1
     779517 10

    设备请求最大逻辑块统计

    root@demo-1:~/flash_seq# awk 'BEGIN{FS=",";max=0};{if($1==0&&$2>max){max=$2}};END{print max}' Financial1
    500363
    
    root@demo-1:~/flash_seq# awk 'BEGIN{FS=",";max=0};{if($1==1&&$2>max){max=$2}};END{print max}' Financial1
    1351642016

    由此可以推断出:
    我们至少需要1351642016×512B的磁盘空间才能满足trace的需求。因为一个扇区512B,换算下来:需要空间就是1351642016/2 (KB)
    也就是说给出的地址其实是逻辑扇区地址,而不是真正的物理地址。

    请求块大小:

    root@demo-1:~/flash_seq# awk 'BEGIN{FS=","};{print $3}' Financial1| sort |uniq -c| head
         38 0
     679197 1024
       9078 10240
          1 102912
       1467 10752

    根据SPC文档的规范,size的单位是byte,例如:65536byte为64k。这样也就说通了。

    运行时间:

    root@demo-1:~/flash_seq# awk 'BEGIN{FS=",";max=0};{if($5>max){max=$5}};END{print max}' Financial1
    43712.242187
    
    或者直接 tail 就行

    根据SPC文档的规范,时间的单位为s,可以看到实际上只是系统运行了12小时的纪录。

    提取指定列

    awk 'BEGIN{FS=","};{print $2, $3, $4 }' Financial1 >>Financial02
    396047 3584 w
    753921 3072 w
    753921 3072 w
    68566 3072 w
    60382 2560 w

    更改指定列

    root@demo-1:~/flash_seq# awk 'BEGIN{FS=" "};{if($3~/r/) {$3="read"} else {$3="write"} print  }' Financial02 |tail
    94970 2048 read
    129870 2560 write
    145658 2048 write
    
    
    awk 'BEGIN{FS=" "};{if($3~/r/) {$3="read"} else {$3="write"} print  }' Financial02 >>Financial03

    格式规划

    awk 'BEGIN{FS=" "};{ {$4="/dev/mapper/cachedev"}  print $4,$3,$1,$2 }' Financial03 |head
    /dev/mapper/cachedev write 303567 3584
    /dev/mapper/cachedev write 55590 3072
    /dev/mapper/cachedev write 303574 3584
    /dev/mapper/cachedev write 240840 3072
    /dev/mapper/cachedev read 55596 3072
    /dev/mapper/cachedev write 303581 3584
    /dev/mapper/cachedev write 55596 3072
    /dev/mapper/cachedev write 303588 3584
    /dev/mapper/cachedev write 55596 3072
    /dev/mapper/cachedev write 303595 3584
    
    awk 'BEGIN{FS=" "};{ {$4="/dev/mapper/cachedev"}  print $4,$3,$1,$2 }' Financial03 >>Financial04

    添加行首和行尾

    awk 'BEGIN{FS=" "};{if(NR==1) {$1="fio";$2="version";$3="2";$4="iolog"} print  }' Financial04 |head
    
    awk 'BEGIN{FS=" "};{if(NR==2) {$2="add";$3="";$4=""} print  }' Financial04 |head
    
    awk 'BEGIN{FS=" "};{if(NR==3) {$2="open";$3="";$4=""} print  }' Financial04 |head
    
    root@demo-1:~/flash_seq# cat Financial04 |wc -l 
    5334987
    
    root@demo-1:~/flash_seq# awk 'BEGIN{FS=" "};{if(NR==5334987) {$2="close";$3="";$4=""} print  }' Financial04 |tail

    Financial Management

    题目

    Larry graduated this year and finally has a job. He’s making a lot of money, but somehow never seems to have enough. Larry has decided that he needs to grab hold of his financial portfolio and solve his financing problems. The first step is to figure out what’s been going on with his money. Larry has his bank account statements and wants to see how much money he has. Help Larry by writing a program to take his closing balance from each of the past twelve months and calculate his average account balance.

    输入格式

    The input will be twelve lines. Each line will contain the closing balance of his bank account for a particular month. Each number will be positive and displayed to the penny. No dollar sign will be included.

    输出格式

    The output will be a single number, the average (mean) of the closing balances for the twelve months. It will be rounded to the nearest penny, preceded immediately by a dollar sign, and followed by the end-of-line. There will be no other spaces or characters in the output.

    Sample Input

    100.00
    489.12
    12454.12
    1234.10
    823.05
    109.20
    5.27
    1542.25
    839.18
    83.99
    1295.01
    1.75

    Sample Output

    $1581.42

    题意

    题目:拉里今年毕业,终于有了一份工作。他做了很多的钱,但不知何故,似乎永远不会有足够的。拉里已经决定,他需要抓着他的金融投资组合,并解决其融资问题。第一步是要弄清楚什么是已经持续了他的钱。Larry拥有自己的银行账户报表,并希望看到他多少钱。帮助拉里·编写一个程序来把他的期末余额在过去的12个月内,计算其平均账户余额。
    输入:12行。每一行是一个月的收入。收入的数字是正数,精确到分。没有美元符号。
    输出:一个数字,是这12个月收入的平均值。精确到分,前面加美元的符号,后面加行结束符。在输出中没有空格或其他字符。

    代码

    #include<stdio.h>
    int main()
    {
        double sum=0, ave, i, n;
        for(i=0;i<12;i++)
        {
            scanf("%lf", &n);
            sum = sum+n;
    }
        ave = sum/12;
         printf("$%.2lf", ave);
        return 0;
     }
